8 Claims.A

The vpresent'invention relates to smoking pipe structures and more especially to pipe structures having an .arrangement for controlling the firing of the tobacco therein.

.An object ofzthepresent invention is to provide a pipe structure and arrangement of the members thereof for enabling a userto control, -as desired, the @ring of the tobacco therein.

.Another .important object of the present in- -vention is to .provide a pipe structure which is economical to manufacture, yet can be readily cleansed, and is, lat the same time, capable Vof providing assm'oke which is cool and which has hadobjectionable heavy oils, tars and lwater vvapors condensed therefrom. y

A further :object of "the present invention is to provide'a-simple, economical and efficient device for controlling the supply of tobacco within a smoking pipe.

Other objects of the present invention will be partly obvious and in part pointed out in the following detailed description of the accompanying drawing. f

In the drawing:

Fig. l6 is an -enlarged detail fragmentary View.

f Referring now more particularly to the accompanying drawing wherein like reference characters designate like members, numeral II designates a tubular member havingsubstantiallyan L-shaped configuration and which member is to lbe formed preferably from a lightweight metal vor a plastic composition. Said member I is formed to correspond toafsmoking pipe bowl 2 which has extending'from the base thereof a stem portion 3. Said :stem portion 3 hasdetachablyconnected -to the free endl thereof .a mouth- (Cl. ISL-@181) piece 5 .by means of a flange portion y1 :of the mouthpiece 5 overlapping end 4 of :said stem. Formed longitudinally .of mouthpiece 5 is an opening or bore 6 .which is fin connection 'with the interior' of stem 3. vAt thev opposite rend .of 5 member I, that' is, upon the open end of bowl 2, is detachably mounted a heat :insulating .ring I2'.

Ring I2, which may :be yformed from meerschaum or other heat insulating material, hfas located centrally thereof `a bore I3, which Abore lo tapers 4outwardly as at I4. .Beneathftaperedportion Itis connected toring I2 at extendedportion IB'thereof, a metalliczthreadediring l5 which is Vconnected tosaid ring IZinany knownmanner such Sas, for example,"by.oooling ring I`.5,'.po 15 sitioning it within .extended yportion I6 and allowing to Warm .and expandinto position. l

The bowl portion 2 `of tubular .member =I has a .flange I8 extending inwardly substantially v`at right .angles therefrom and which flange has fur- 20 ther formed perpendicular vtherewith a threaded ring I1. Said threaded ring I1 is sized and shaped for receiving in threaded .engagement metallic ring 'I5 and thereby detachably connectingring I2 `upon flange I8 and theupper edge of ring I1. The outer wall of ring V`l2 is shaped and sized in order to cooperate :with k'the outer wall of vbowl 2 in order to completetherewith the appearance .of a smoking pipebowl. Likewise, tapered portion I4 o'f bore (I3 extends Ifrombore I3 .to the inner .side of ring I1 and thereby Aforms a continuous `smooth walled bore from bore 'I3 tothe lower edgev of `ring I1.

Said tubular member `I has formed in its 'interior :face situated at the base of the bowl'portion thereof a recess 3|, the wallsof'which form a regular decagon. f

A' regular decagonal `walled tube 31 preferably formed of alightweight metal isinserted within bowl 2 through ring I'1 .during the rem'oValtherefrom of ring I2 and Vthebase end 35 thereof is situated within said recess 3l vin such a manner that recess 3| performs the function of a socket therefor, prohibiting lateral or rotary movement thereof. Each of the ten walls '32 forming the tube 31 .form at their connection'to .one another ten corners 34. Ring I1 of bowl Z'Ybeing cylindrically shaped and tube 31 being formed'of straight walls 32, it results that only Ythe corners 34 of the tube 31 contact the ring I1 and, therefore, '50 walls 32 form with said ring `I1'spaces `or passages 33 :therebetween and yet tube 31 is vprevented from lateral movement by contact'ofthe corners 34 with the ring I1.

An `opening 40 is .formed through tube :l fiat 'a 55 central portion of said recess 3l. Positioned through said opening 4B is a section 2'! of a telescopic arrangement consisting of sections 22, 23, 24, 26 and 2l. Section 2'! has a peripheral ila-nge 28 formed therewith which rotatably supports section 2'! within the recess 3I and, at the same time, closes opening 40. Upon the portion of section 2'! extending beyond the tube member i, there are formed a series of righthand threads 29. Screwed upon section 2'! is a knurled knob i9 having a bearing portion II, which portion lI I contacts the outer surface of tubular member I, thereby closing opening 40 and cooperates with peripheral ange 28 to retain section 2l in place but allowing rotary movement thereof. The inner wall of section 2'! has formed therein lefthand threads 30, which threads are in threaded engagement with further threads formed upon the outer surface of a second section 26, which section 26 is of a diameter and length which per mits the same to be rotated to a position entirely within the bore of section 21. Likewise, sections 26, 24v and 23, which have lefthand threads 25 formed upon their outer periphery and also lef"- hand threads 3U formed in the upper portion of their inner wall, are in threaded engagement with one another, as shown, and are sized in order that they may be rotatably telescoped one within the other.

Reference number 20 designates a plate or disc, the edge of which forms a regular decagonA and which plate 29 is capable of being positioned within and extending across the bore of tube 3'! with the edge of said plate 20 being in slidable` contact with the walls 32 forming the bore 36 of the tube 3l. Plate 29 has extending from a central pointv thereof a'threaded projection 2i, which is in threaded engagement with a threaded section 22, which in turn is in threaded engagement with threads 36 formed upon the interior wall of aforementioned section 23.

Situated within the interior 8 of tubular mern`y berA I is tobacco or other filtering material 9 but which material 9 is excluded from within the tube 3'! and fills passageway 3B formed bythe interior of bowl portion 2 of tubular member I and the exterior face of tube 3'!.

In assembling the present device, telescopic section 22 is screwed into section 23, section 23 into section 24, section 24 into section 26 and section 26 into section 21, each section being in'- serted through the bottom of the receiving section until the entire series of sections are nestled within section 21, as shown in Fig. 3. Plate 29, by

:means of projection 2l is connected to section 22 and these connected members are inserted past ring I'! until flange 28 contacts the interior face of tubular member I, at which time knurled knob IU by a righthand rotation, is screwed onto threads 29 of section 2'! until portion II o-f the knob contacts the exterior face of tubular member I and is sufficiently tight thereagainst to permit the knob `Ill and section 2'! to rotate and yet completely enclose opening 40. Decagonal tube 3? is then'in'serted through ring I 'l until end 35 thereof is positioned within the recess 3l. Ring l2 is, by threaded engagement of metallic ring I5'with ring I'I of bowl 2, screwed into position upon said bowl 2, at which time tapered bor-e I4 `will be gradually lowered until it contacts or is just within point of Contact with corners 34 of tube 31. This contact of bore I4 with said corners 34 retains tube 3'! within the bowl 2 and recess 3! thereby preventing lateral, longitudinal or rotary movement thereof. Fresh tobacco or other filtertube 3i upon said plate 26 until the bore 36' and a portion of the bore I3 are filled therewith. Upon a flame being applied to the tobacco `and the user of the pipe drawing inwardly through bore 6 of mouthpiece 5, air will be drawn through bore I3 to supply the necessary oxygen to y assist in the combustion of the tobacco within the bores 36 and I3, whereby the smoke therefrom will be drawn through openings 33, as shown by the arrows in Fig. 2, to within passageway 38 and then through the ltering medium 9, due to the suction created in the interior 8 of th-e tubular member I by the user drawing, as aforementionedr upon the mouthpiece 5. As the tobacco is consumed by burning, the user, by giving knob I9 a righthand rotation, will cause section 2'! to une' screw from section 26 until the section 26 reaches the blank portions 39 `of the periphery thereof, whereby rotational movement between sections 2? and 26 will thereby be stopped and upon continued righthand rotation of knob I9, section 26 in its now fixed position, will unscrew from sec-r tion 24 until threads 30 contact blank portionsv 39 upon the periphery of section 24 andthe same L effect will be carried through with regard to sections Mand 23, and 23 and 22. The unscrewing of these sections one from the other, will cause. plate 23 to be progressively advanced and at the same time, due to the decagonal shape of the plate 2D and tube 3l', said plate 26 will not lbe permittedto rotate and, therefore, will preventy the rotation of section 22, thereby assisting in the ,L unscrewing of the sections from one another upon their respective rotational movement. In this manner, the tobacco can be continuously `and progressively fed to the upper end of bore 36 and to within bore I3 whereby the smoke from the burning portions thereof will travel through openings 33 and not through the remaining portions of the tobacco within said bore 36.

Tubular member I being of a lightweightlmetal or plastic will readily conduct heat from the interior thereof, thereby cooling all smoke therein causing the condensation therefrom of objectionable heavy oils, tars and water vapors, which condensation products are absorbed by the ltering medium 9 and thereby present through theA mouthpiece 5 a'cool, dry smoke. The ring I2 being of a heat insulating material will retain the heat from the burning tobacco' therein and will not conduct said heat to the tubularmerri` ber l and metallic tube 3'! being at all times cov'-v ered with fresh tobacco, will thereby be insulated against the heat of the burning tobacco and will likewise remain relatively cool. Thus, the fresh tobacco within bore 36 will remain cooland vdry until presented and also smoke stored within passageway 38 will be given a chance to cool and condense the' objectionable ingredients there? from. l

When the user of said smoking pipe desires to discontinue smoking, he may give knob IU a leftsaid knob IIJ with the sections 22,A 23, l24, 26 and hand rotation and through the connection of" other,1gpla`te'20 =willibe-caused to be lowered, carrying therewith -the ltobacco i`9 Ysupported therebyuntil fthe rtobacco'is lowered within `the bore 36-w`herelitiwill r'emainforiuse atlother times.

Tubular ymember `P3'I hasbeen disclosedin the drawing having a decagonal wall, but said tube 3l may have *thew-all l-thereof partially cylindrical and with the cylindrical portions connected by substantially straight Wall portions. Plate 20 should have the edge thereof shaped to correspond to the cross sectional configuration of bore 36 in order that the plate 20 cannot be caused to rotate while positioned therein. Also, the exterior conguration of tube 31 should be so shapedas to provide with ring I1 a passage or passageway 33 therebetween.

Whereas the telescopic section as shown and described comprises four' sections besides section 21, a greater or smaller number of like sections may be used equally as well.

My invention is capable of considerable modiflcation but such modification as comes within the scope of the appended claims, I deem to be within the spirit of my invention.
